The other example I think is kinda the reverse, opinions can change how you feel about the game even though nothing truly changed - think it was League where a patch was agreed to have fixed a character and later the devs realised they forgot to actually implement the change ingame

League sparks me of the only problem of data-driven choices is that it falls into the space of how good the company is at interpreting data.

I am still bitter on them removing Hunter's Potion "because it was a loosers' item" when the problem was it only catered to an already losing crowd (tanks)

League specific problem is how they only view data through the lense of every player and every character, every item and every rune needs to win 50% of their matches or it's not balanced.
Which is one of the most insane approaches to data in a random matchmaking of 5v5 people environment.
